What is the future of gravure ink? Teacher Tsai points out five directions

Gravure ink has always been hotly debated and concerned. In 2016, this word appeared repeatedly in major reports or news headlines. Gravure ink and wash ink has indeed made some technical progress, and even some sounds of successful testing have continued to spread. Whether it is a case or a general policy, it still needs to wait for the inspection of the industry. With regard to the future application of thin-film gravure printing ink, we should focus on what areas. Teacher Cai Chengji gave the following five suggestions. Although the article is short, it contains a lot of valuable information and I hope that people in the industry can study it carefully.

The question of the adhesion of ink on the film is no longer a problem with the development of ink-and-wash technology in this year, but it must be evaluated very calmly. At present, it is the key technology that has completely mastered the choice of water-based resin, or only passed the test. With trial, accidentally got a certain resin applied? If there is a change in supply channels, what will happen to inks that are suitable for thin films?

In the field of ink-jet leveling and shrinkage holes, when the ink-and-ink manufacturing technology is still defective, the ink-and-wash application unit must use its own characteristics to make up for it. This works well for flexo printing processes that already have a relatively complete theoretical structure, but for gravure printing processes that have been extensive for many years, it is necessary to work hard.

The solvent content of ink and wash is the environmental protection department has been staring at it. Since 2007, when its own product standards have been up to 30%, the main reason why ink is still placed in VOCs fixed pollution sources is now covered. Therefore, even though flexo paper inks with a solvent content of 5% or less have been accompanied, they do not enjoy the same treatment of the same class of products in foreign countries. In China, they must also be treated according to the requirements of environmental protection. Pay sewage charges. In fact, flexo printing ink and ink can be removed by cutting before the cap, but most of the film ink can control at 5%? Can the ink manufacturing process be achieved? Is it necessary to add so-called thinners that contain solvents?

When the printing industry requires both environmental protection and cost, thin-film inks with a solvent content of less than 5% are preferred. In this way, we will make our sky bluer and clearer without increasing costs. Therefore, it is imperative to revise the ink product standards that were implemented in 2007. When the environmental protection department meets the industry's cost and emission treatment technologies in accordance with the terminal emissions policy, it is worthwhile to reform from the source and use the ink-based water-based process route.

It is necessary to take into account the difficulties in the compounding process of thin-film ink printing. The combination of solvent-free compounding and water-based glue must be compared with quality, cost, and productivity issues as soon as possible. Prepare a pre-plan and wait for the temporary wearing of the chair to wear the ear.

Xiaobian message

In 2016, it was also known as the Environmental Protection Year. In that year, the VOCs sewage charges blew over more than half of China. Gravure printing companies faced the challenge of life and death under this wave of environmental protection, and the gravure printing ink was Driven by this momentum, we have indeed made a big step forward. There are news reports about the success of soft packaging companies in testing ink painting. There is no shortage of ink solutions from ink suppliers, or they are delighted or wait-and-see. I think industry players should Adhere to rational treatment, not let the interests blind their eyes, there must be less than the Yellow River's determination to die.

At the beginning of 2017, the printing technology magazine of the printing press will continue to follow the progress of the film gravure printing ink, and present the most objective report for you. In 2017, let us continue to pay attention to each other and work together for a win-win situation!
